When I select a RAW-Image and select edit in PS CS 6 the image is opened in photoshop and everythings seems to work find. But after saving the image (as tiff, using default settings) nothing habens in LR - the image is not imported into the catalog.

When trying to sync the folder manually, the first dialog shows that one image (this image) will be added, but then an error message is shown that no image has been imported.

This is a problem with my big main catalog which has been migrated from LR 3, but it works fine when creating a new catalog.

Also importing the existing huge catalog into a new catalog did not solve the problem (but the images edited within the old catalog were shown).

So it seems that LR does only a partial "import" when editing images in CS6.

I believe the option not to save a compatibility mode preview is only effective for PSD not TIFF, but that may be worth checking. LR needs there to be such a preview in the file, if it has layers - which it cannot otherwise decipher.

The error message suggests that LR can see that the image exists as a file, but cannot use it as a functioning image. "Sync Folder" should not have been necessary - if Save was selected instead of Save As, in Photoshop, LR should already have been looking out for that particular filename.

So renaming removes LR's difficulty - that is a useful clue. What are your LR external editing settings doing? For example, mine adds a "-edit" suffix to the starting filename. Could you post an example of an automatically named filename which does not work?

I would have expected there to be some difficulty or warning notification when saving the file in CS6. But maybe a control code or unusual character may have been included somehow in the instructions it has been given, which CS6 thinks it is OK to save, but LR does not think it is OK to import.

... but I think this is just a lightroom bug which has to be fixed by Adobe.

Christian,

That might be the case, but in order to fix a problem it has to be

reported properly

As far as I can judge from reading here, something seems to be wrong with your catalog, as you don't have any problem with a newly created catalog. So Adobe will NOT be able to reproduce what you're seeing unless you can supply them with your catalog.

If "sync folder" shows the edited TIFF in the filesystem but is then not importing anything, one explanation may be: this image IS already in the Catalog; but Lightroom's current view has filtered it out so it is not displayed.

This might not be the case - and I hesitate to suggest the too-obvious (though the too-obvious is often what trips us up , even the most experienced). But it does at least fit with having the problem in one Catalog but not in another... if one Catalog happens to be set to show its images in some selective way which excludes these image versions.

Library screen / Catalog panel / "all photographs"; then Grid view / Filter bar / "None"; then Photo menu / Stacking / "expand all stacks"; then View menu / Sort / "Capture time" (or the same operations done another way) should either eliminate, or confirm. You should then see each and any edit version that is present, right next to its related original.
